Stylistically, JDS vs Cain reminds me a lot of Chuck vs Randy.
And given the style match-up, Cain CAN beat JDS, but he has to be perfect. He can't make even ONE mistake. JDS can hit and miss because he only needs to make one shot count.
Stylistically, JDS is just a nightmare for Cain, but Cain is obviously still very very good and capable of winning if he doesn't make any mistakes.
